It is a viral vector vaccine based on a human adenovirus that has been modified to contain the gene for making the spike protein of the SARS-CoV-2 virus that causes COVID-19

Chinese CoronaVac and the Sinopharm BIBP and WIBP vaccines; the Indian Covaxin; later this year the Russian CoviVac; the Kazakhstani vaccine QazVac; and the Iranian COVIran Barekat.
But those are probably much harder to get for readers in Western countries. And they’ve generally been found to be less effective, I think; possibly because the inactivation process damages the proteins.
